Hasta La Gadget!

Is there anything lasers can’t do? We only ask because they seem to be improving everything from microphones to railroads, and now researchers from Purdue University have leveraged the power of light to better manufacture solar cells. Using an ultrashort (as in quadrillionths of a second) pulse laser to more precisely scribe the microchannels connecting thin-film solar cells — as compared to current mechanical stylus methods — the Boilermakers were able to improve energy transfer efficiency between cells and significantly reduce manufacturing time. Having demonstrated the process works, research continues to better understand and prepare it for use by manufacturers — sooner rather than later, we hope.

This as-of-yet-unnamed mini computer was fashioned as an implantable eye pressure monitor for glaucoma patients, but its creators envision a future where we’re all crawling with the little buggers. Taking up just over one cubic millimeter of space, the thing stuffs a pressure sensor, memory, thin-film battery, solar cell, wireless radio, and low-power microprocessor all into one very small translucent container. The processor behind this little guy uses an “extreme” sleep mode to keep it napping at 15-minute intervals and sucking up 5.3 nanowatts while awake, and its battery runs off 10 hours of indoor light or one and a half hours of sun beams. Using the sensor to measure eye pressure and the radio to communicate with an external reader, the system will continuously track the progress of glaucoma, without those pesky contacts. Of course, the mad scientists behind it look forward to a day when the tiny device will do much more, with each of us toting hundreds of the computer implants all over our bodies — looks like a bright future for cyborgdom.

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

This week Inhabitat saw high-speed railways pick up steam around the globe as China announced plans to build a trans-continental railroad in South America and Japan began developing the world’s fastest high-speed train. We also saw eco transportation reach new heights as a kite-powered car completed an epic 5,000km journey across Australia and researchers developed a nanotech paint that will increase the fuel efficiency of airplanes. The automotive world is also gearing up for the Geneva car show as Toyota is getting set to roll out an all-electric IQ and Porsche pulled back the curtain on its Panamera S Hybrid and Boxster EV.

In other news, this week we brought you an exclusive video interview where celebrated environmentalist Stewart Brand argues that nuclear power could save the world. We also explored several other alternative energy sources that are decidedly less controversial – PurposeEnergy is transforming beer brewing waste into a source of clean-burning biofuel, and a design duo has proposed a series of beautiful solar-powered artificial trees that scrub CO2 from the air.

Roughly one in every six people do not have access to safe drinking water, so we were excited to learn about a pedal-powered water purification system based on the bicycle that holds great promise for the developing world. Speaking of cleaning up dirty water, this week Stephen Baldwin sued Kevin Costner over the oil-separating technology that cleaned up the BP oil spill. And last but not least, we were wowed by this hydrofloor system, which can save space and energy by concealing a swimming pool beneath your living room floor!

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

This week Inhabitat shed light on the next generation of solar power as we showcased a spray-on film capable of generating 300% more energy than traditional photovoltaics and a new breed of nanotech cells that can heal themselves like plants. New biofuel projects also broke ground around the world as the US began construction on its first commercial biofuel plant and Canada upgraded a waste plant to be powered by soda and beer. And another farticle, er, article covers a project in Greenpoint, Brooklyn that takes the result of the results of those drinks (methane) and turns it into fuel.

We also interviewed energy efficiency expert David Johnston, who shared 5 tips that could cut your electricity bill by up to 50 percent. And on a more sour energy efficiency note, we were appalled to see this new study that found that LEDs, like CFLs, also contain unsafe levels of carcinogenic toxins. The big (or should we say B.I.G) architecture news of the week was the unveiling of Bjarke Ingels Group’s sloping residential pyramid for midtown Manhattan.

In transportation news, Nissan revealed plans to roll out its Tesla-trouncing ESFLOW electric supercar at the Geneva Auto Show, while Chevrolet announced that the Volt will receive a $5,000 tax rebate in California. We also applauded the US government’s $53 billion plan to jump start high speed rail, while republicans rallied against the movement towards more efficient infrastructure.

We also showcased several stylish examples of wearable eco tech – a set of bio sensors that improve physical and emotional health, and a pair of GPS-enabled snow goggles that are perfect for shredding through uncharted territory. Finally, we shared 10 green iPad cases that are perfect for protecting your e-reader from blustery winter weather.

Solar power is the most egalitarian of all energy sources, yet residents in many parts of the world still lack access to electricity. Three University of Michigan engineering students have created an affordable solution to this problem — to the delight of camping geeks everywhere — with the Emerald, a portable solar panel that does double duty as both a cellphone charger and personal light source. We’ve seen the personal solar panel idea before, but the price of entry made it an untenable solution for developing nations. Solar-powered light bulbs have been around for a while too, but the Emerald’s light lasts for eight hours on a charge (as opposed to the bulbs’ two to six hours), and it’s able to fully charge a phone in the same time it takes an outlet to do the job. They aim to sell the device for the low, low, price of under twenty bucks for customers in the developing world, which is 90 percent cheaper than other solutions and 100 percent more awesome.
